Public bug reported:
Steps to reproduce:
1. Begin Ubuntu user session with Unity
2. Open Terminal and run: sudo iwconfig
After doing this, the end result varies--either the entire screen is
replaced by a terminal window showing the kernel error, or the Unity
session appears to continue but all running windows stop responding and
the computer cannot be restarted from Unity (need to use power button on
laptop).
My laptop has the BCM4331 wireless card and it's being managed by the wl
driver. When running sudo iwconfig, I was connected to an auto-mode
802.11b/g/n router (I believe I was connected via wireless-N because the
link speed shown was 144 Mbps).
